WINDING DEVICE.

Application and June 23, 1923. Serial No.,647, 413.

To all 107mm it may concern:

Be it known that I, THOMAS P. LITTLE, a citizen of the United States of America, residing at Chicopee Falls. in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in a Winding Device, of which the following is a specification.

This invention relates to a winding device especially adapted for winding up with a lining or separating material strips of rubberized fabric as they are severed by a suitable cutting device. The device has been illustrated as applied to the winding up of strips severed on the bias from a web of fabric, as for example by a bias cutting machine shown in the patent to Bolton 942,164, dated Dec. 7, 1909. but it finds application to the winding of fabric strips generally.

The invention has for one object the winding of successively severed strips without any pause being necessary for changing the winding rolls, or any variation being required in the location in which the strips are placed. The device is thus made applicable to steady operation of the cutting device. and to a mechanical device for trans fcrring the severed strips from the cutter to the winder if desired. It has for another object the facilitation of the handling of the rolls of lining material or wound-up strips. Other objects and advantages will appear from the following description and claims.

The invention will now be described with particular reference to the accompanying drawings, in which- Fig. 1 is a side elevation of the machine;

Fig. 2 a section on line 22 of Fig. 1;

Fig. 3 is a plan View;

Fig. 4 is a diagrammatic section illustrating one winding position;

Fig. 5 is a similar view illustrating another winding position; and

Figs. 6 and 7 are details on line 66 of Fig. 1 illustrating two positions of the roll supporting means.

The machine comprises a frame 10, preferably inclined as shown in case the winding device is used with the vertical bias cutter of the type shown in the Bolton patent, supported at either end by brackets 11. The upper of the two brackets 11 is carried by a pedestal 12 having a platform 13 attached thereto upon which a workman maystand in handling the upper end of the bias strip.

. Journaled in each bracket 11 are rolls 14 and 15. each carrying a gear 16 meshing with a common gear 17, whereby the two rolls will rotate together at the same speed and direction. Roll of each set carries a pulley 18 connected by a belt 19 with a pulley 20 loosely mounted on a counter shaft 21 journaled in a frame 22. A pulley 23 fast to the counter shaft is connected by a belt 24 with a pulley on the shaft of a motor 25. Clutches 26 connect either of the pulleys 20 to the counter shaft for rotation therewith in a known manner, being operated by shifting levers 27. These shifting levers may be mounted for individual operation, as is desirable when the two winding units are to be operated both together and separately during the working of the machine, or as in thecase shown they may be connected by a link 28 and controlled together by a handle 29 so that when one pulley 20 is operating the other is idle. Such clutch mechanism is common in countershaft construction for various purposes and need not be described in more detail.

Frame 10 carries on either side series of freely turning rollers 30 and 31 respectively, rollers 30 being grooved and rollers 31 un grooved to prevent binding of the slide supported thereby. Running on these rollers, and guided laterally by the grooves in roll- (31'8'30, is a slide 32 having a flat top (preferably of smooth metal) and depending side portions engaging the rollers. To the center of the top edge of the slide is attached a cable 33 passing over a sheave 34 journaled in frame 10 and carrying a weight 35 adapted to counterbalance the slide and permit it to be shiftedeasily up or down by a handle 36 located on its side. At its upper end the slide carries a latch 37 adapted to engage the handle 29 when the slide is at its upper position and the handle is in position to cause operation of the lower of the two' rollers 15. This both supports the slide in its upper position and provides "for the release of the latch when the handle is shifted to start the operation of the other winding unit.

Associated with the; mechanism thus far described are devices (Figs. 6 and 7) for supporting rolls of lining materials and permitting their ready displacement. These devices being in duplicate a description of one will sutlice for both. Each comprises a bracket attached to frame 10 and supporting grooved rollers 41 and 42 and a track 43. A sliding frame 44 has a track 45 engaging rollers 41 and 42 and carries a grooved roller 46 engaging track 43. Frame 44 has hooked portions 4? adapted to support an arbor 48 carrying a roll 49 of lining material. By this construction the frame can be rolled out to a convenient position (Fig. 7 and the unit at the right in Fig. 8) so that an empty spool may be easily replaced.

Other elements and features of construe lion will be best understood in connection with the operation of the machine. Assuming the slide to be initially at the upper limit of travel, as shown in Fig. 4, the lining material a from the right hand roll 49 is led over a flanged guide 50 attached to the frame 10, over a roller 51 on the slide, over a roller 52 on frame 10 and to an arbor 53 which is placed between rolls 14 and 15. By giving the material a few turns around the arbor 53 it will be wound thereon by surface contact with the rolls when these are rotated by the connections described. No winding is done on the upper winding unit when the parts are in the position of Fig. 4, winding in this positionbeing on the lower unit.

When the spool being wound on the lower unit is completed-the slide is released from its upper position by shifting lever 29 and is quickly moved to the lower end of frame 10. Fig. 5 represents the condition at this period. it will be noticed that a relatively long expanse of the liner a". is provided between rolls 51 andv 52, this expanse occurring at one end or the other of the slide, depending upon whether the latter is at the upper or lower end of the frame. The purpose of this is perhaps best seen from. Fig. 3, in which the relation of the parts is as in Fig. 4 and the operative liner (z is passing from the left hand supply spool 49 to an arbor on the lower oi the winding rolls 14, (Fig. 4). In Fig. 5 two successive strips Z) of bias cut material are .hown, one almost entirely wound on the spool 53 and the second one just placed on the machine ready for winding. This secend sheet lies partly on the table top and partly on the liner.

The purpose of the shifting slide may now be considered. its the bias cutting ma chine always delivers the stock-in one place it is impracticable for the operators to deliver it to the winding device other than in one place. This is even more marked in cases where delivery from the bias cutting machine is by automatic means. In order to wind up the stock so delivered it is laid upon the web of lining material which carries it into the spool in' its travel. The surface of the slide being smooth will not appreciably retard the motion of the. strips, as would be the case if the trailing end of the strip had to rest on a stationary liner web.

Having thus described my invention, 1 claim:

1. A winding device for strips of material comprising a pair of winding mechanisms adapted to wind the material with'a web of lining material, a slide located between the winding devices, and guide rolls at each end of the path of travel of the slide over which a liner web may pass, whereby when the slide is at one end of its travel an expanse of liner Web is provided at the other end.

2. A winding device adapted to wind strips of material between turns of a liner web, comprising a plurality of winding mechanisms each adapted to wind a separate liner web, a table located between the two liner webs and movable into a position adjacent either one or the other of the Winding mechanisms, liner guides carried by the table, and means for shifting the table so as to present within a constant strip placing area a portion of the table and a portion of either of the liner webs.

3. A winding device adapted to wind strips of material between turns of a liner web, comprising a pair of winding mechanisms each adapted to wind a separate liner web, and mechanism operable to shift either of the liners into a constant strip placing area and to remove the other liner simultaneously from. said area.
